This invention relates to implements for removing roller bearings from the aide housings .of motor vehicles, and has for its obj ect the provision of an improved implement of this character to facilitate the removal of such roller bearings.

To this end the' invention consists the novel construction, adaptation and combination of parts hereinafter described anc claimed.

ln the accompanying drawing,

Figure 1 is a view partly in longitudinal section .and partly in side elevation of devices embodying our virurention shown applied. Fig. 2 is side elevation of the implement; and Fig. 3 is an end elevation of Fig. 2.

1n said drawing, the reference numeral 5 represents an axle extending through a housing 6 which, at its outer end, is provided with a cylindrical cavity 7 to receive a sleeve S which serves as the outer bearing for a roller bearing assembly, which assembly hereinafter designated as the roller bearing. Said roller bearing, as shown, consists of a plurality yof rollers 9 arranged concentrically about the journal portion of said axle by the provision of studs such as 12 which are carried in spaced relations by means of annular retainers 13 at opposite ends of the rollers. rllhese retainers are of greater internal diameter than the diameter of the axle journal and areconnected with each other and to said rollers in a manner to permit a limited axial movement of the rollers vith respect to the retainers.

The portion 15 of the axle which protrudes from the housing is formed of a conical shape to engage within acorresponding aperture of a vehicle wheel, not shown.`

rlhe above described parte are, or may be, of any known or suitable construction.

rEhe implement which constitutes the subject of the present invention comprises a tuiular expansion member 16 and a tubular operating member 17.

The expansion member 16 is formed eXteriorly with substantially cylindrical rear portion 1S. a forwardly tapering intermediate portion 19 and a front portion 20. Said front portion 2O is desirably of aconoidal shape the forward extremity being of larger diameter and thence the portion 2O tapers rearwardly as best shown in Fig. 2te

afford with the periphery -of the portion 1.9 recess extending circumferentially aro-und the memb r.

Adjacent `its rear end said expansion member is formed i-nteriorly to provide.

screw threads 21 :and adjacent its forward end is provided with ai tapering peripheral surface 22.v Said expansion member is furthermorel slotted longitudinally yas at 23 from its forward end to apertures such as 231 to aord fingers 24, eachhaving a substantially hook-shaped ,forward extremity.

The operating member 17 is provided intermediate its lengt-li with vscrew threads 25 engaging the internal threads 21 of the eX- pansion member to effect relative axial movement of the operating member when the latter is independently rotated within the expansion member. When the expansion member 16 is held against rotary motion and the operating member 17 suitably rotated to thrust its forward end 26 against the Vtapering'peripheral surface 22 of the eXpansion member, the lingers of the expansion member are forced radially outward. When the operating member is retracted from its engagement with the surface ,22, the re-v siliency of the expansion member lingers effeet the relative contraction of the same, the fiexure of the fingers occurring principally at the portions thereof of reduced width between the adjacent apertures'281.

To permit the two members to be readily grasped inthe hands of an operator, portions of the outer peripheral surfaces are desirably lniurled as at 27 and 28, respectively.

ln the practice of our invention, the implement is applied over the aXle part 15 with the hooked ends of the lingers 24 insert ed within the opening of the adjacent retainer 13. Thus arranged the operator holds in one of his hands the expansion member 16 from turning and with his other hand rotates the operating member 17 which is thereby thrust forward to cause the fingers to be relatively expanded to engage the re- -t-ainer above referred to.

. The device is thus coupled with the associated roller bearing assembly which is eX- tracted from the axle housing by withdrawing the devicefrom the axle.

Thilo we have described the invention in its construction now preferred byl us. it is to be understood that we do n ot wish to coniine ourselves specifically thereto except as limited by the scope of the appended claims.

What We claim, is,-

l. In an implement for removing a rollerbearing assembly from a vehicle axle, a tubular member slotted at the front end to provide a plurality of fingers, said fingers being formed With relatively tapering inner surfaces and substantially hook-shaped outer 2 surfaces, screw threads provided interiorly of said member adjacent its rear end, and a second tubular member adapted to receive the axle end therein and provided intermediate its length With external screw threads engaging the screw threads of the first named member, said second named member being adapted When moved in one axial di rection to engage the tapering surfaces of said fingers to distend the latter radially of the axle into engaging relation With the roller bearing assembly.

2. in an implement for removing a rollen bearing assembly from a vehicle axle Within the axle housing', a tubular member the front end of which is provided with quadrifid slots to provide a plurality of fingers, said slots terminating in apertures of greater diameter than the Widths of the respect-ive slots to provide a relatively Weak area between the apertures at opposite sides of each linger, said fingers being formed With relatively taperg ing inner surfaces and substantially hookedshaped outer surfaces, screw threads provided iuteriorly of said member adjacent its rear end, and a second tubular member adapted to surround the axle Within the first named member provided intermediate its length with external Screw threads engaging the screw threads of the first named mem` ber, sald second named member being adapted when moved 1n one axial direction to engage the tapering surfaces of said fingers
